This product does not emit light of its own, so the standard review format will not be used and the product will not be assigned a rating

The Pocket View-ItŪ NIR Detector Card is used to view NIR (near-infrared) radiation that would otherwise not be visible to the eye.

The rounded-off square on the left side of the card is sensitive to NIR radiation from 800nm to 1700nm; its peak response appears to occur right around 1064nm -- this is the frequency of a YAG laser -- the type of laser used in such things as yellow, green, and blue laser pointers.

This card uses an anti-Stokes phosphor, meaning it will convert the NIR radiation it is irradiated with into a visible green light; and it does not to be "charged" with visible light prior to use like other types of NIR detector cards do.

This is Kentek Laser part number VW-PKT-IR.

Photograph of the card being irradiated with the NIR laser line from this product.
The glow is actually green; the camera imaged the NIR radiation itself much more strongly than the green glow from the card, resulting in the green glow (which is highly visible to the unaided eye) to be overwhelmed.

Spectrographic analysis
Spectrographic analysis of the glow from this card when irradiated by the NIR radiation from this product.
That spectral feature at ~473nm is almost certainly the laser's native emission, and could not be completely eliminated with the filters at my disposal.

Spectrographic analysis
Repeat spectrographic analysis of the glow from this card when irradiated by the NIR radiation from this product.
The laser's native emission line at 473nm is greatly reduced this time because I used more filters (Roscolux #40, #41, and #42 simultaneously).

It is not known where the product was manufactured.
A product's country of origin really does matter to some people, which is why I wanted to publish it on this web page.
